6.5-284 Norma: A Precision Long-Range Cartridge

The 6.5-284 Norma is a high-performance rifle cartridge known for its exceptional accuracy and long-range capabilities. Developed from the .284 Winchester case necked down to 6.5mm, this cartridge has gained popularity among long-range shooters and competitive marksmen. With its flat trajectory, high ballistic coefficient, and moderate recoil, the 6.5-284 Norma has become a favorite for precision shooting disciplines and long-range hunting.

History and Development

The 6.5-284 Norma originated as a wildcat cartridge in the 1960s. It was created by necking down the .284 Winchester case to accept 6.5mm (.264 inch) bullets. The cartridge gained popularity among long-range shooters due to its excellent ballistic properties and accuracy potential.

In 1999, Norma of Sweden standardized the cartridge, leading to its commercial production and wider availability. This standardization helped increase its popularity and led to more rifle manufacturers offering firearms chambered for this round.

The 6.5-284 Norma quickly gained a reputation in long-range shooting competitions, particularly in disciplines like F-Class and 1000-yard benchrest. Its combination of high velocity, flat trajectory, and excellent wind-bucking ability made it a formidable cartridge for precision shooting at extended ranges.

While primarily used in competitive shooting, the 6.5-284 Norma has also found a niche in long-range hunting. Its ability to deliver high energy at extended distances while maintaining manageable recoil has made it popular among hunters pursuing game at longer ranges.

Ballistic Performance

The 6.5-284 Norma typically fires bullets weighing between 120 and 142 grains. These bullets have high ballistic coefficients, contributing to the cartridge's excellent long-range performance. Muzzle velocities range from 2900 to 3200 feet per second, depending on the bullet weight and load.

The cartridge's performance is characterized by a flat trajectory and high retained energy at long distances. It maintains supersonic velocity beyond 1000 yards, making it suitable for extreme long-range shooting. The 6.5mm bullets used in this cartridge are known for their ability to resist wind drift, further enhancing long-range accuracy.
